A parish about 25 minutes from me did a major renovation to a round church design, entirely different building. The prior church was made in the 90s I believe and it looked like a rec center, all chairs. So in comparison, the round church is actually very beautiful, it has kneelers now, massive stain glass windows, and a huge marble structure going up to the ceiling holding the Tabernacle.
I’ve gone to mass there a few times and I’d say it’s a huge improvement from the old parish but it’s not my cup of tea, there is awkwardness with the choir being crammed in a corner and the Priest doesn’t sit on the Sanctuary, he sits in the congregation in the front pew with everyone else lol. But it’s probably the most beautiful round church I’ve seen, I think they did a great job (a notoriously known parish for “not following the rules” shall we say… so this was quite the improvement)
